I have lots of Java Moss, some (10-20 stems) Heteranthera, and lots (40+ plants) of Dwarf Sagittaria. (most of the Dwarf Sag is taller than the pic- See http://www.aquaticplantcentral.com/forumapc/plantfinder/details.php?id=77 for more details on the Dwarf Sag).
Could include some Vallisneria as well.
All for $20, probably enough to plant out a 40-50 gal tank, or will split the bunch for $12 each.
